A blizzard is a powerful snowstorm with strong winds and heavy snowfall. Blizzards can make it hard to see and travel because of blowing snow. They can cause icy roads, power outages, and extreme cold temperatures. The intensity of a blizzard is measured by how much snow falls, how strong the winds are, and how long it lasts. People should stay indoors during a blizzard, keep warm, and avoid driving. Wearing multiple layers of clothing and staying hydrated helps protect against the cold. Blizzards can be beautiful to watch from inside, but it’s important to be prepared and safe.
